Creepy Bunny with red 3mm LED eyes (parametric for Openscad Customizer)

The customizable bunny is a model of a sitting rabbit, with many body parameters adjustable by the user (e.g. in Openscad or with customizer).

Head direction can be adjusted, as well as size and shape of body and ears. This special version adds the feature to insert 2 x 3mm LEDs as illumination, which gives a creepy “glowing eyes” appearance. 

The model prints w/o any support, any PLA or other filament should work. White PLA looks nice with red eye illumination (some glowing appears, see the pictures).

Use 2 x 3mm ultrabright LEDs connected in series and add a 100..200 Ohm resistor to get it running at 3..5V (e.g. 1 Lipo cell) for many hours.

Added Features:
 - Allover Scaling selectable in Customizer
 - Hollow Head selectable on/off in Customizer
 - 3.5mm LED tubes behind both eyes, selectable on/off in Customizer
